It is the only direct train from Hyderabad to Rameswaram, runs once in a week. This train starts from Okha and goes on till Rameswaram. It is very difficult to get a confirmed reservation for this train. I don't know why the Indian Railways has not considered to increase the frequency of the train to the Historical and ancient town of Rameswaram. I planned my travel with wait list in 2AC, for my self and my 72 year old mother. Fortunately my ticket got confirmed just 20 hours before my Scheduled time of Departure. In fact I tried my luck. But the train reached the destination only 30 minutes late after very long journey of about 25 hours from Hyderabad to Rameswaram.
